Letters .Patent No. 106,285, lated August 9, 1870.

IMPROVEMENT IN' BOOK-HOLDERS.

The Schedule referred to in these Letters Patent and marking part of thesame To all whom tt may concern.-

Be it known that we, ELIAS PRorsT and JAMES F. AVIS, of Tipton, Vin thecounty 'of Tipton and State of Indiana, have invented certain new anduseful Improvements in Adjustable Book-Holders, which we have describedin the iollowing specilication, and `illustrated in the accompanyingdrawings, with suficient clearness `to enable others of. competent skillto make and use our invention.

Figure l isa perspective view of our improved book-holder, showing Athebase upon which it rests,

the adjustable column or standard which rises out of said base, and theadjustable book-rack, which is attached to the topl of such standard.

yFigure 2 is a vertical elevation, with portions broken away to show.the method of making the attachments.'

Figure v3 is a vertical `sectional elevation, showing the manner ofattaching the standard to the base.

Corresponding letters refer to corresponding parts in the severaliigures.

This invention relates to book or paper-holders; and Y It consists inthe construction, combination, and arrangement ot' its parts, as willvbe more fully described hereinafter, the object being to provide anadjustable frame for. holding booksor papers for copying, reading, orfor any other purpose, in such a manner as that any desired angle orinclination may be given to them.

A refers to a base for supporting theother parts of the devices, whichmay be of the form shown, or of any other desired form, which will admitof there being formed at its center a recess or cavity for the receptionof the lower end of the standard, and permit- 'ting its movementtherein.

B refers to a standard or column, which may be of wood or of metal, andof any required diameter and length, it being provided with a collar orenlargement upon its lower end for entering the cavity in the base, asshown in iig.. 3.

In the upper end ot' this standard/a hole or Socket is formed for thereception of a pin or projection which is formed upon the arm C, aset-screw passing through the standard, or a portion ot' it, as shown intig. 2, and thus-providing the means of holding the said arm in anydesired position. Y

At the lower end of this standard there is a rod or pivot, which permitsthe-standard to turn to a certain extent 'in the base, in order thattheposition of the rack F, upon which the books or papers are placed, maybe made to assume any desired angle, or a greater angle than can begiven to it by theother parts soon to be described.

Through one portion of the base A there is to be formed a screw-threadfor the reception ot a set-screw, for the purpose of holding thestandard when it has been placed `in any desired position.

oted, in such a manner that it may be turned from a vertical position ton early a horizontal one.

The opposite arm tothe one above described en tends out-ward, and iscurved, as shown, its outer portion being slotted to receive the dog D,which is p iv` oted to such slot in such a manner that a projection uponits under side may be made to engage with thel teeth of the rack E,Aasshown in fig. 2, and thus hold it in any desired position.`

-E refers to the rack above alluded to, which is pivoted to thebook-rack or holder F, as shown in tig. 2, and so arranged that itsouter end will pass through the slot in arm- C, and be held in positionby dog D.

F refers to the frame ot'` wood or metal, it being provided with agroove in its bottom rail for the reception of the edge of the books orpapers to be held, its center rail being hinged to the arm G, so that itmay be turned, as above described.

VThe operation of this device will be as follows:

The parts having been constructed and arranged as .shown in tig. 2, thebooks or papers are to be placed upon the fi'alne F, whmen it may bemade to assume any angle, with reference to the horizon, within therange of rack or bar E, in'which position it may be secured by the dogD.

Whenever the amount ot' angularity given by the above-named parts is notsutticient, an additional arnountmaysbe given by turning the standard inthe base A, and it may be held in the desired position by thc set-screwtherein.

It will be seen that, as a consequence of the two -methods of givinginclina-tion to the frame or rack F, it may be made to assume anyposition between a vertical and a horizontal one, and that, by means ofthe pivot ou arm C, it .may be made lto revolveentirely around, so thatany degree of angularity may be given at the same time.

Having thus described our invention,

W'hat we claim, and desireto secure by Letters Patent, is

l. A book or paper-holder, the standard of which is adjustable at itslower end, substantially as and for the purpose set forth. i

2. The combination and 'arrangement of the adjustable standard B, varmC, rack E, and rack or frame F, substantially as and for the purpose setforth.

JAMES F. AVIS.
